Gettysburg battlefield looking down at Devil's Den from Little Roundtop

Confederate troops tried to take Little Roundtop, a volcanic knoll that would have given them the ability to attack Union troops from the weakest side. But valiant efforts by Maine and other units prevented this. Conferederate sharp-shooters hiding within the cavities in Devil's Den (see accompanying image) did damage, but were unable to turn the tide. In the valley between these two features, more than 8,000 men from both sides died, and the stream ran red with their blood.
